STORAGE-RACK.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed May 31, 1912. l Serial No. 700,793.

To all whom it may concern:

Be it known that I, FRANK KUHN, a citizen of the United States of America, resid ing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Storage Racks, of which the following is a specification reference being had therein to the accompanying drawings.

The invention relates to storage racks designed for use in warehouses, stock rooms and other places where it is desirable to store articles as compactly as possible and so as to be accessible.

It is the object of the invention to obtain a fireproof construction which may be manufactured at small cost from standard metal bars, and which possesses strength and rigidity, and can be adapted to receive any size of box or storage receptacles.

In the drawings: Figure l is a perspective view of a portion of the storage rack. Fig. 2 is a horizontal section thereof. Fig. 3 is a vertical section. Fig. l is an enlarged section showing one of the joints.

The structural elements which I employ for forming my improved construction of storage rack are angle bars of standard form and size. These bars are punched, slitted and bent to form the various members, the detail construction being as follows: A are vertical bars or stanchion members, which are properly spaced from each other by horizontally extending bars B arranged at intervals. Both bars A and B are angles and the bars 13 have their horizontal flanges provided with V-shaped notches C adapted to receive the bars A with their flanges an ranged at substantially a 45 degree angle to the plane of the bars B. The bars A and B are then secured to each other by bolts D passing through the angles and the vertical flange of the bar 13 and secured by a clamping nut E. The two sides of the rack are thus formed by bars A and B secured as described and parallel with each other. These two frames are then cross connected by horizontal bars E, which also form supports and slide-ways for the individual boxes or re ceptacles in which the articles are stored. The bars E are also angles and to permit of attachment to the angularly arranged bars A the flanges E are slitted at E so as to permit the vertical flanges E to be bent into conformity with the flange of the bar A. These bent portions are then secured by bolts F in passing through punched or drilled registering apertures in the adjacent flanges. If desired at one end of the bars E the slitting may be parallel with the vertical flange as shown at E" so as to leave a longer flange E, the end E of which is turned up to form a stop limiting the movement of the box or receptacle.

The bars B may be reinforced by oppositely arranged truss bars G placed with their vertical flanges abutting against those of the bars B and secured thereto by the bolts D. The frame is further strengthened by diagonal truss bars G arranged at suit able intervals and connecting the opposite bars A as shown.

The structure as described can be readily manufactured in any shop provided with a punch-press or drillpress and may be made to accommodate any space available. When completely erected suitable receptacles are provided of a size to fit between the vertical bars or stanchions A and of a height to occupy the space between the successive cross bars E. These receptacles are accessible from either one or both sides of the rack and may he slid out on the horizontal flanges E. All of the parts being formed of metal the structure is obviously fireproof.

What I claim as my invention is:

1. A storage rack comprising parallel, vertical angle bars spaced from each other with their apices extending oppositely, angle cross bars connecting said vertical bars, having their horizontal flanges slit and their vertical flanges bent to conform to the angle of the flanges of said vertical bars.

2. A storage rack comprising parallel vertical angle bars having their apices extending oppositely, horizontally extending angle bars connecting said vertical bars, their horizontal flanges being slitted to permit the vertical flanges to be bent into conformity to the angle of said vertical bars, and bolts for securing said horizontal and said vertical bars.

3. A storage rack comprising a series of pairs of parallel vertical angle bars with their apices extending oppositely, horizontal angle bars arranged in the planes of the bars on opposite sides of the bars and notched to form seats for said vertical bars, bolts for connecting said horizontal and said vertical bars passing through the apices of the latter and horizontal cross bars between the members of the bars having their horizontal flanges slitted to permit the vertical flanges being bent into parallelism With the flanges of said vertical bars, and bolts for securing said bent flanges to said vertical bars.

4. A storage rack comprising a series of pairs of parallel vertical anglebars having their apices extending oppositely, horizontal angle bars having notched flanges forming seats for said vertical bars, bolts passing through the apices of said vertical bars and the vertical flanges of said horizontal bars, anddiagonal truss rods extending between the opposite vertical bars of a pair, andhaving their ends passing through the apices of said bars and adjacent flanges of the horizontal bars.

5. A storage rack comprising pairs of parallel vertical angle bars having their apices extending oppositely, horizontal bars connecting the corresponding members of said pairs of vertical bars, horizontal cross bars connecting the membersof the same pair of vertical bars, the horizontal flanges of said cross bars being slitted and the vertical flanges being bent at the slit to lie adjacent to the flanges of said vertical bars.

In testimony whereof I afiix my signature in presence of two witnesses.
